技术问答

辰达行推出的ESD0524P是一款超低电容的瞬态电压抑制二极管阵列（TVS二极管阵列），能为高速数据接口提供保护。其电容典型值仅0.2pF（I/O到I/O），可保护寄生敏感系统，使其免受过压和过流瞬态事件的影响。ESD0524P符合IEC 61000-4-2（ESD），等级4（±15kV空气放电，±8kV接触放电）、IEC 61000-4-4（电快速瞬变，EFT）（40A，5/50ns）、超快速充电器件模型（CDM）ESD和电缆放电事件（CDE）等的要求。

ESD0524P采用超小型的DFN2510塑料封装，每个器件可保护4条高速数据线。ESD0524P具有超低电容、超小尺寸和高ESD稳健性，非常适合高速数据端口和高频线应用，如HDMI和DVI，其低钳位电压可最大限度地减小所保护的IC受到的电压应力。

ESD0524P ESD保护二极管阵列的特点：

· 为非对称数据线提供瞬态保护

· IEC61000-4-2（ESD）：±25kV（空气放电）、±20kV（接触放电）

IEC61000-4-4（EFT）：40A（5/50ns）

电缆放电事件（CDE）

· 针对高速线优化的封装

· 保护4条数据线

· 低电容：0.2pF（I/O到I/O）

· 低漏电流

· 低钳位电压

· 每个I/O引脚可承受超过1000次的ESD冲击（±8kV接触放电）

ESD0524P ESD保护二极管阵列的机械参数：

· 封装：DFN2510

· 阻燃等级：UL 94V-0

· 端子：镀雾锡

· 可高温焊接：260℃/10s

· 丝印：0524P

· 包装：编带和卷盘

ESD0524P ESD保护二极管阵列的应用：

· 串行ATA

· 高清晰度多媒体接口（HDMI）

· 台式机、服务器和笔记本电脑

· 为USB 2.0/3.0电源线和数据线提供保护

· MDDI端口

· 显示端口

· PCI Express

· 数字视频接口（DVI）
